The average depth of the ocean is about 3,700m. The deepest point in the ocean known today is Challenger Deep in the Mariana Trench with a depth of about 10,935m (nearly 11km).

Despite living in harsh environmental conditions such as the deepest ocean trench, these creatures still thrive.

People heard strange moans mingling with a low sound, occasionally interfering with a screeching cry like a violent storm.

American scientists have drawn the deepest area map in the ocean, more detailed than the previous maps. It is the Mariana basin in the western Pacific Ocean, about 2500km long and

Twelve people have walked on the Moon, but only three people dare to venture into the Challenger Deep abyss of the Mariana Trench, the deepest point on the ocean floor.
